I'm positive that this kind of asking is inappropriate. That's why my first answer (deleted) was so "offensive".

The asker that constructed the question to look like

When attchng file, to Ques; what is "must be 3 pts."?

doesn't show any sign of respect to those who the question is addressed to, who may want to help. The question must be deciphered, both in language (missed letters that make words look like puzzles), and in data (answerer must guess that attachment is being made to this site's question, not to Calc that is mentioned as keyword; must reconstruct the full context that is the full message text - not only last (jammed) words of it).

A proper question would look like "When I try to attach a file to a question on this site, I get an error message saying "To attach files, you must have at least 3 points karma". What does it mean? What do I need to do to be able to create attachments?". In current form, I believe that the question does not deserve to be answered, though @peterwt was kind enough to bother about it.

Also, best not to answer your own question, with a question as you have here. If you enter an "Answer" it should be an answer. Sorry to be hard on you. Everyone has to learn this stuff initially. Just try to ask good questions that are super clear and you're likely to get good answers here. And please be sure to spell things correctly at a minimum.
